Craigend Castle is a ruined country house, located to the north of Milngavie, in Stirlingshire, central Scotland.
The lands of Craigend were part of the Barony of Mugdock in medieval times, but the estate was sold in the mid-17th century to the Smith family.
It was built by Alexander Ramsay, initially using designs by James Smith of Jordanhill, in what is described as Regency Gothic style.
Glasgow businessman Andrew Wilson and his zoologist son, William, bought part of Craigend Estate from the Buchanan family and opened a zoo at Craigend Castle and stables in 1949, with various exotic animals, but it failed to attract significant visitors and eventually closed in 1955.
The stable block, located to the north of the house, now serves as the country park visitor centre.
